| titleOfInvention | Method for detecting total iron content in iron ore |
| abstract | The invention belongs to the technical field of iron content detection, and discloses a method for detecting the total iron content in iron ore, which comprises the steps of weighing a sample in a conical flask, adding a small amount of water, adding mixed sulfuric-phosphorus acid and perchloric acid, decomposing the sample at high temperature until a sample solution is clear, and emitting thick white smoke; adding a hydrochloric acid solution and 40mL of water, heating and boiling to dissolve salts, taking down, adding a sodium tungstate solution, standing, dropwise adding a titanium trichloride solution to enable a sample solution to be light blue, and standing for 1-2 min; adding 120-150 ml of water, adding copper sulfate to ensure that blue color just fades away, immediately adding sodium diphenylamine sulfonate solution, titrating to a stable purple color by using a potassium dichromate standard solution, and calculating the total iron content according to a formula. The method for detecting the content of the total iron in the iron ore has the advantages of rapidness and effectiveness for a sample dissolving method, less used chemical reagents, no serious harm to human bodies, convenient operation steps and capability of effectively solving the dilemma of deviation of the result of the existing method for determining the content of the total iron in the iron ore. |
